FEELER: LA2A PCB with build manual

Hi There!

I finally finished my LA2A PCB and made some units with it, and it works good. I post here to see if there is any interest in a first run of PCB. Price is 50$USD + shipping. This is NOT a kit, only a feeler for the PCB itself, unpopulated. Some hints:

The psu integrate the option to use a Toroidal or EI power transformer,
The use of DC for V1 heaters
The integration of a bleeder resistor
Plenty of filtering on the PSU, for better ripples rejection
Audio transformers are mounted outboard
Tested with Cinemag transformers.
Complete build manual
A link for a mouser and Digikey card
Exel sheet BOM
My eternal gratitude

PCB Color; Black, blue or green?  8)

Allright you're in haha.

Blue PCBs!

What was your total cost for building on of these? Can you make the compression link switchable?

Thanks!

One vote for blue! toral cost turn around 900 to 1100$CAD. Must be a bit less in USD haha. By compression link switchable, you mean compression on/off ?

I just began to upload the build manual and stuff. Let me know what you think. Follow the link on the first post.  8)

I meant to say stereo linking the compressors. The other thing made no sense.

Thanks!

Paul

I put a stereo link pad so yes, you can stereo link it

Only need 8 7 more person/board and I'll be good to start a first batch  8)

Potato cakes, are you in?

Unfortunately, I think I'm going to have to pass this time. I have too many projects to finish, which is compounded by the fact that I am traveling frequently right now. I'll have to check back later this year and see if they are still available. It seems to be a quick and easy way to get build and LA2A.

Thanks!

Paul

Looks good.  Just wondering what the differences are between this and Silent Arts D-LA2A version?

Hi

The D-LA2A is a dual version on one board, mine is a mono board. Other than that, I think the main difference is in the psu. But that's about it.

got any gut shots of the finished unit?

I found very little pictures, but here we go!
